What are the reasons for the high fuel consumption of the Maxus?
4 Answers
Reasons for excessive fuel consumption include: 1. Lack of maintenance: The vehicle has not been maintained for a long time, causing the engine oil and air filter to become dirty, leading to increased fuel consumption. 2. Aging: The engine spark plugs have aged, and excessive carbon buildup affects ignition efficiency, resulting in higher fuel consumption. 3. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the ground, raising friction and driving resistance, which in turn increases fuel consumption. 4. Excessive carbon buildup: Carbon deposits can accumulate in the throttle, fuel injectors, intake ducts, and piston tops. Excessive carbon buildup in any of these areas can lead to incomplete combustion, thereby increasing fuel consumption.
After driving my S-MAX, I noticed a sudden increase in fuel consumption, mainly due to my aggressive driving habits. I always tend to stomp on the accelerator and brake suddenly, and driving too fast on the highway increases wind resistance, which definitely raises fuel consumption. Even at red lights, I often accelerate and then brake hard, wasting fuel repeatedly. Additionally, I frequently overload the car with heavy items, which naturally increases the burden and fuel consumption. I suggest trying to drive more smoothly, accelerating and decelerating gradually, and using the air conditioning less or controlling the fan speed appropriately in the city. After developing better habits, my fuel consumption dropped significantly, saving me money and making driving safer. These small adjustments may seem simple, but they add up to save money and hassle—definitely worth a try.
As an automotive maintenance technician, common causes of high fuel consumption in the Maxus include lack of regular maintenance. Worn spark plugs lead to delayed ignition and incomplete combustion, wasting fuel. Clogged air filters reduce intake efficiency, naturally increasing fuel consumption. Insufficient tire pressure increases friction resistance, which also consumes more fuel. Additionally, excessive carbon buildup in the fuel system, such as in the fuel injectors, can cause over-spraying and waste. It is recommended to inspect and replace these components every 5,000 kilometers to maintain cleanliness and efficiency, avoiding severe issues. By performing these basic maintenance tasks, the engine will run smoothly, fuel consumption will stabilize, and the vehicle's lifespan will be extended.
I found that the increased fuel consumption of the S-MAX is mainly due to engine component issues, such as a faulty oxygen sensor. It sends incorrect signals, causing the ECU to inject more fuel, leading to waste. Carbon buildup in the throttle body affects the air intake, resulting in an unbalanced fuel mixture and a surge in fuel consumption. A worn fuel pump causing unstable fuel supply can also worsen fuel consumption—these are all hidden faults. Regularly cleaning the throttle body and checking sensors is crucial. Early repairs can prevent more problems and improve driving smoothness.
